When I was a teenager, I used to take my 3 y/o sister to the beach with me all the time and the girls would be attracted like seagulls to french fries. Not very ethical to use my sister like that, but it got me a lot of dates that a scrawny computer geek wouldn't have been able to get on his own. My parents used to tell everyone that I was the best big brother ever because I went everywhere with my baby sister.
